-Applic ati0n filed June 16, 1927. SerialNo. 199,181.;

My' invention relates to method of and apparatus for dispensing liquids and is particularly designed for the production of a device for handling syrups and beverages of all kinds and especially those sold at soda fountains. More especially my invention. contemplates absolute uniformity in the bever-.

ages dispensed regardless of their density;

the elimination of unnecessary waste; the

use of simpler and more reliable apparatus; as well as greater output, the ability to em.- ploy less experienced operatives and to dis pense with greater sanitation. 7 I p The beverage dispensing apparatus at present used in soda fountains, comprises a plunger pump mounted on the cover of the syrup container, a spout adjacent the pump for leading the syrup from said pumpto the glass to be filled; and manually controlled means for operating said pump. It has been found in practicethat such plunger pumps are not sanitary, easily get out of order and cannot be relied upon to dispense uniform quantities of liquid on successive strokes of the plunger. It is therefore necessary for soda fountain operatives to manipulate these pumps manually in accordance with their own judgment instead of relying on the capacity of the pump to give the desired amount at a single stroke; This results in lack of uniformity in the beverages, even where experienced operatives are employed; and also wastes time by necessitating several strokes of the pump to deliver the proper amount of liquid. I

In my invention a gas such as the usual carbonated gas, or air under a constant-and predetermined eressure obtained by gravity or by a separate pump forces the syrup into a bottle of definite capacity, the liquid flowiug into the bottle until the pressure of the air or gas trapped in the bottle is equal to and the pressure of the actuating gas and.

as both of these can be definitely fixed, the amount dispensed is always the same. The

size of bottle is such that one operation of the device dispenses the desiredamount of liquid, thereby savlng time and requlring no discretion onfthe part of the operative.

As the onlymoving part of the entire appa-. ratus is the rotating .element'of the valve, long and reliable service with a minimum of up-keep results from the use of my invention.

In the drawings which illustrate one em- 2 bodiment ofthe invention. I

Fig. 1 is an elevation partly in sectlon of the measuring bottle and control valve;

v 2 is a section along the line 22 of Fig. 1 showing the valve in position toconneot the bottle with the. source of liquid sup- .Fig. 3 is similar to Fig. 2, but shows the valve in discharging position; and 1 ;F.ig. 4- diag ammatically'zshows my inven- .tion applied to a soda fountain.

.Referring to Fig; ft; :1 denotes generally a soda fountain of conventional design beneath which is located a tank 2, for compressed air or gas, the pressure in the tank being kept constant by any well known means, not shown. The tank is connected to a distributingpipe 3, by means of pipe 4-, and pipes 5 connect the distributing pipe with thereceptacles '6, for the various syrups. The recepta cles 6 may be of any desired construction and are here shown as being the usual jar or demijohn provided with cap 7, it being necessary to close valve 8 before removing the-cap. Pipe 9 connects the receptacle 6 with the inlet side of the two-way valve 10 which con- The valve itself (see Figs. 1,2 and 3) is 7 made of brass or other suitablematerial and coli'l n'ises a lowerdisk 14, and an upper 'rolary disk 15, the two parts being held in close contact by meansof stud 16, nut 17 and spring 18. Adjacent surfaces of the disks are ground and washer 19 of leather-or similar material is further provided to insure a. leak proof fit.

The lower disk is provided with a port 2Ov connected to the intake pipe 9 and a port 21 connected to the outlet pipe and spout 12, a

nut 22 on the outlet pipe may serve to clamp the valve to a part of the fountain or counter l. The upper disk is provided with two passages 23 and 24, which are adapted to register with the intake and discharge pipes respectively. Said upper disk is further provided with a threaded recess 25 for receiving the neck of the glass yessel tight joint being secured by using a resilient washer 26. Disk 26 is rotated by means of handle 27 to either intake, exhaust, or neutral position. Lugs 28 and stop finger 29 insure accurate registering of the ports in both intake and exhaust positions,

In operation, tank 2 is tilled with a compressed gas or air and receptacles 6 are filled with various syrups, and then handle 27 is turned until the valve is in the position shown in Fig. 2. This connects the intake pipe 9 with the interior of the measuring vessel and allows the gas in tank 2 to force syrup into vessel 11 until the pressure of the gas trapped in the top of said vessel balances the pressure of the gas in the tank. The operative then turns the valve until the passage 24 connects the interior of the vessel with the 'discl'iarge pipe and spout 12 when the compressed gas in the vessel 11 forces the syrup out of the discharge pipe 12 and into the customers glass which is held under said pipe. After the discharge of the syrup the valve is preferably returned to neutral position to preventthe possibility of any dirt accumulating in the measuring vessel. Furthermore there is no after dripping of the liquids for following the rush of the liquid from the measuring jar there will be created a relatively partial vacuum which will suck back into the jar any liquid adhering to the spout. IWh-ere space permits it has been found entirely satisfactory to raise the liquid container 6 a sutficient height to give the required pressure by means of gravity and thereby eliminate the necessity of any other means for creating a pressure upon the container.

In carrying out my invention the liquids may be put into sterilized containers and also the liquids themselves may be sterilized therein. Since the entire system is closed to the atmosphere there is no possibility of contamination oi any sort thereby insuring a sanitary dispenser.

Without limiting myself to the particular apparatus shown, I claim:

In fountain apparatus for dispensing beverages, a tank for containing compressed gas, a receptacle for holding a beverage, said receptacle being in communication with said tank, a valve-controlled closed rigid measuring vessel, and a rotary valve for supporting said vessel and capable of connecting said vessel either with said receptacle or with the at mosphere.

In w tness whereof, I hereunto subscribe my signature.
